The wildlife in India comprises a mix of species of different types of organisms.[1] Apart from a handful of the major farm animals such as cows, buffaloes, goats, poultry, and camels, India has an amazingly wide variety of animals native to the country. It is home to Bengal tigers, Indian lions, deer, pythons, wolves, foxes, bears, crocodiles, wild dogs, monkeys, snakes, antelope species, varieties of bison and the Asian elephant. The region's rich and diverse wildlife is preserved in 120+ national parks, 18 Bio-reserves and 500+ wildlife sanctuaries across the country. India has some of the most biodiverse regions of the world and hosts three of the world’s 34 biodiversity hotspots – or treasure-houses – that is the Western Ghats, the Eastern Himalayas and Indo- Burma.[2] Since India is home to a number of rare and threatened animal species, wildlife management in the country is essential to preserve these species.[3] India is one of the seventeen megadiverse countries. According to one study, India along with other 16 mega diverse countries is home to about 60-70 % of the world's biodiversity.[4]

The varied and rich wildlife of India has had a profound impact on the region's popular culture. The common name for wilderness in India is jungle, which was adopted into the English language. The word has been also made famous in The Jungle Book by Rudyard Kipling. India's wildlife has been the subject of numerous other tales and fables such as the Panchatantra.

The Indian leopard is found across the Indian subcontinent. Poaching for its skin is a serious threat to the leopard.

The need for conservation of wildlife in India is often questioned because of the apparently incorrect priority in the face of direct poverty of the people. However, Article 48 of the Constitution of India specifies that, "The state shall endeavor to protect and improve the environment and to safeguard the forests and wildlife of the country" and Article 51-A states that "it shall be the duty of every citizen of India to protect and improve the natural environment including forests, lakes, rivers, and wildlife and to have compassion for living creatures."[11]

Large and charismatic mammals are important for wildlife tourism in India, and several national parks and wildlife sanctuaries cater to these needs. Project Tiger, started in 1972, is a major effort to conserve the tiger and its habitats.[12] At the turn of the 20th century, one estimate of the tiger population in India placed the figure at 40,000, yet an Indian tiger census conducted in 2008 revealed the existence of only 1,411 tigers. 2010 tiger census revealed that there are 1700 tigers left in India.[13] As per the latest tiger census (2015), there are around 2226 tigers in India. By far, there is an overall 30% increase in tiger population. [14] The passing of the Forest Rights Act by the Indian government in 2008 has been the final nail in the coffin and has pushed the Indian tiger to the verge of extinction. Various pressures in the later part of the 20th century led to the progressive decline of wilderness resulting in the disturbance of viable tiger habitats. At the International Union for the Conservation of Nature and Natural Resources (IUCN) General Assembly meeting in Delhi in 1969, serious concern was voiced about the threat to several species of wildlife and the shrinkage of wilderness in India. In 1970, a national ban on tiger hunting was imposed, and in 1972 the Wildlife Protection Act came into force. The framework was then set up to formulate a project for tiger conservation with an ecological approach. However, there is not much optimism about this framework's ability to save the peacock, which is the national bird of India. George Schaller wrote about tiger conservation:[15]

The exploitation of land and forest resources by humans along with hunting and trapping for food and sport has led to the extinction of many species in India in recent times. These species include mammals such as the Indian/Asiatic cheetah, wild zebu, Javan rhinoceros, and Sumatran rhinoceros.[16] While some of these large mammal species are confirmed extinct, there have been many smaller animal and plant species whose status is harder to determine. Many species have not been seen since their description.

The diversity of fungi[19] and their natural beauty occupy a prime place in the biological world and India has been a cradle for such organisms. Only a fraction of the total fungal wealth of India has been subjected to scientific scrutiny and mycologists have to unravel this unexplored and hidden wealth. One-third of fungal diversity of the globe exists in India. The country has an array of 10 diverse biomes including Trans-Himalayan zone, Himalaya, Desert, Semi-Arid zone, Western Ghats, Deccan Peninsula, Gangetic Plain, North-Eastern India, Coasts and Islands where varied dominating regimes manifest. This enables the survival of manifold fungal flora in these regions which include hot spot areas like the Himalayan ranges, Western Ghats, hill stations, mangroves, sea coasts, fresh water bodies etc. Many fungi have been recorded from these regions and from the country in general comprising thermophiles, psychrophiles, mesophiles, aquatic forms, marine forms, plant and animal pathogens, edible fungi and beneficial fungi and so on. The number of fungi recorded in India exceeds 27,000 species, the largest biotic community after insects. The true fungi belong to the Kingdom[20] Fungi which has four phyla, 103 orders, 484 families and 4979 genera. About 205 new genera have been described from India, of which 32% were discovered by C. V. Subramanian of the University of Madras.[21][22] These features indicate a ten-fold increase in the last 80 years.

The Indian government has established eighteen biosphere reserves of India which protect larger areas of natural habitat and often include one or more national parks and/or preserves, along buffer zones that are open to some economic uses. Protection is granted not only to the flora and fauna of the protected region, but also to the human communities who inhabit these regions, and their ways of life.
